A new Progress freighter spacecraft carrying more the 2.5 tons of supplies for ISS was launched from the Baikonur Cosmodrome in Kazakhstan at 11:25 p.m. EDT Friday. The spacecraft is carrying fuel, air, water and other supplies and equipment for the space station.

The ISS Progress 25 unpiloted cargo carrier that is using the automated Kurs system to dock at the aft port of the Zvezda Service Module is scheduled to arrive Tuesday at 12:10 a.m.

On Tuesday, Yurchikhin and flight engineers Suni Williams and Oleg Kotov tested communications between the station and the docked ISS Progress 24. On Wednesday, in recognition of the Russian holiday Victory Day, marking the end of World War II, the crew performed only necessary station activities.

Once its cargo is unloaded, Progress 25 will be filled with trash and station discards. It is scheduled to be undocked, deorbited and be incinerated upon re-entry July 20.

Expedition 15 crew members, Yurchikhin and flight engineers Sunita Williams and Oleg Kotov, will continue to use oxygen from the Progress 24 at the Pirs Docking Compartment. It is scheduled to remain there until mid-August.
